Modbus ASCII on ESP32

Greetings. I am working on a project with ESP32 DEV Module. I am having problems with communication between a Delta DVP-12SE PLC and ESP32 MCU on Modbus ASCII. I have a lot of Arduino and ESP32 MCU on my work desk. I also have a Delta DVP12-SE. I have tried the Modbus RTU protocol with various configurations and communicated successfully (Ex: 8E1-8E2 8O1-8O2 8N1-8N2). However, I am having trouble finding a working Modbus ASCII library written for arduino. I want to send information from PLC to ESP32 MCU in various configurations (Ex: 7E1-7E2 7N1-7N2 7O1-7O2). I am looking for a sample code or a working library. thank you in advance for your help.
